OK, after searching through the logs I was able to locate your requests that were triggering the 500 error. Digging a little deeper, it looks like we were having trouble fetching the attachment for one of your dummy bank_account_entries, which probably stems from a recent update we’ve made on how files are handled internally.

I think I’ve fixed everything up now and you should be able to enumerate your transactions once again. Let me know if you have any further problems and thanks again for your patience!
